Chapter 1215 The big plane plan will be completed soon
"When the engine turns on afterburner, its fuel consumption is at least twice that of normal conditions, and the corresponding aircraft's range will also be reduced. Non-afterburner fuel consumption is 0.75-0.8Kg/hour Kg thrust, while afterburner fuel consumption is 1.8Kg
Kg thrust per hour.
At the same time, because turning on afterburner will drastically increase the temperature and pressure of the afterburning section of the engine's internal duct, as well as the speed of the core turbine, turning on afterburner will shorten the engine life.
According to the data of this alloy material, it is still unable to meet the above thrust conditions. Of course, I am talking about the data of third-generation combat effectiveness. The transport aircraft may be smaller, so I will treat it as a ten percent reduction. Even so, this alloy
There is still a certain gap in the parameters of the material. My suggestion is to add a little manganese to this material. The specific amount is not clear. This needs to be tested...
By the way, the maximum afterburning time allowed for Russian jet engines generally does not exceed two minutes, and the maximum afterburning time allowed for jet engines in the United States and Western countries generally does not exceed five minutes. After exceeding this time, the stress on the engine components may exceed the yield strength.
The occurrence of serious problems such as cracks and fractures shows that the strength of the alloy has an upper limit. If the strength is too high, it will cause the cylinder to be willful, which requires a balance point.
In addition, it should be noted that the color of the engine flame is related to the sufficient degree of fuel combustion. If the combustion is complete, it will be blue, and if the combustion is insufficient, it will be yellow. You can also see blue flames and yellow flames at the same time.
When the Russian fighter jet exerts power, the flame appears blue, while the American fighter jet appears yellow. This shows that the Russian engine mainly relies on increasing fuel utilization, while the American engine relies on increasing fuel combustion. Our country's engines cannot copy the other two countries. We must
Find a balance between them. This design is just some of my ideas. You can show the design drawings to the scientific research team."
Well, not many people present could understand what Liu Lang said. Fortunately, what he said was written in the document. It can be said that this document was written for the national large aircraft engine plan. It is a document based on Kam
Based on Sky's materials, the scientific research team can have more purposeful information.
Although this material is completely a theoretical analysis and has not been proved by experiments, every derivation process is perfect and completely logical. Therefore, Liu Lang feels that the feasibility of this material is very high and can be achieved within 10% of the time.
Over eighty.
"It seems that I will report this matter to the superiors immediately after I return. This is likely to be another turning point in the country's large aircraft plan!"
Jiang Botao's idea was not wrong. He had the drawings of the An-225 aircraft engine before, and today he has obtained the information on the new alloy material. Isn't everything ready? When the country launched the large aircraft plan, it was expected to use
In fifteen to twenty years, this
It took a long time, so long that it required the joint efforts of two or even three generations. As a result, God helped China and the Soviet Union fell. Some precious materials accidentally got into the hands of the country. With these precious materials, the country's plan
It shortened almost at rocket speed.
Jiang Botao estimates that this project may achieve a breakthrough within five years, and perhaps the country will be able to build its own large aircraft in this century.
Jiang Botao stayed in Fucheng for three days. In addition to Norinco, he also inspected other manufacturing companies, needless to say, he encouraged everyone.
He felt that this visit to Fucheng was really worthwhile, especially the "Exploration No. 1" CNC machine tool, which made him extremely excited.
Three days later, Jiang Botao left Fucheng and took a noon flight back to the capital. As soon as he arrived in the capital, he reported to Bai Weiren.
"What? Liu Lang built a CNC machine tool?"
Bai Weiren was also shocked after hearing this.
"Yes, I didn't know about this beforehand. I only saw it for the first time when I arrived in Fucheng!"
"Ha, this is Liu Lang's style. I guess he will say: This is nothing. After all, the chip is not independently developed. Is that what he said?"
Bai Weiren said with a smile.
"Premier Ren's guess is absolutely correct. Liu Lang called it a servo system, but he has already cooperated with SMIC to develop his own chip. It is likely that a breakthrough will be achieved within a year. By then, this exploration will
No. 1 is a well-deserved domestic machine tool!”
Jiang Botao still couldn't restrain his excitement when he said this.
"Okay! This little guy is really a genius. There seems to be nothing he can't do. The country's manufacturing industry depends on him. When I go to Fucheng in two days, I must take a look at this machine tool and see what our country's No.
What does a CNC machine tool look like!”
Bai Weiren was also extremely excited.
"By the way, as Prime Minister, this is the information Liu Lang got from Kaminsky. Shougang, Shanghai Iron and Steel and Anshan Iron and Steel all have one copy, and this information was specially designed by Liu Lang for the large aircraft engine project.
A set of improved design drawings, together with the engine materials, he asked me to hand over to expert Qin Lie. I think it is necessary for us to hold another docking meeting and let the leaders and scientific research groups of the three steel plants join forces to form a joint team. I can
Serve as team leader.”
Jiang Botao felt that the national large aircraft project was very important and should immediately hand over these materials to the scientific research team.
"Well, that's a good idea. I'll do what you suggested. By the way, call in all these departments and I'll hold a meeting for them in person. If that doesn't work, I will be the team leader and you will be the deputy team leader!"
"That's great. If Prime Minister Ren serves as the leader of this team, I'm afraid the large aircraft project will be completed in the 1990s."
Jiang Botao called the heads of several departments over according to Bai Weiren's instructions. The headquarters of the large aircraft research and development team is in the capital, but the test base is in Xichuan Province. In addition, the Shencheng Aircraft Manufacturing Factory is also a major department. Experts like Qin Lie
Now he is working so hard that he forgets to eat and sleep. When he heard that he was going to the capital for a meeting, he was a little angry. Even if Bai Weiren personally presided over it, his work has entered the fast lane and progress is made every day. The state only needs to provide money, so what is the purpose of holding meetings every day?
It has no big effect,
But when they heard that Liu Lang was going to give them some precious materials, it was like taking a shot of chicken blood. They got huge benefits from Liu Lang. It was also because of him that the development time of the large aircraft was greatly shortened. Maybe these old people
Everyone can see the scene when the plane takes off.
Mr. Qin hurried to Bai Weiren's office with several assistants. Leaders of various ministries and commissions were present in the conference room. The standards of the meeting were very high.
As soon as he sat down, a secretary placed a stack of documents in front of him.
“So many meeting materials? It’s a waste!”
Mr. Qin muttered for a moment, then flipped through it casually, and was immediately attracted to it.
"Oh my God! What is this... what is this!"
Several assistants on the side also gathered around and stared at him without blinking.
Several people gathered around and looked through this material, their attention completely lost.
